Ecumenical Patriarch Attikos

Ecumenical Patriarch Attikos (360-10 October 425) was the Ecumenical Patriarch of Constantinople from 406 to 425, succeeding Ecumenical Patriarch Arsakios and preceding Ecumenical Patriarch Sisinnios I.

Biography
Attikos was initially an enemy of John Chrysostom, but he went on to support the Ecumenical Patriarch Arsakios in deposing him, although after John's death Attikos became a supporter of him. Attikos rebuilt a small church that is now the Hagia Sophia, and he opposed Pelagianism, increasing his popularity among the people of Constantinople.
